The present invention relates to sheet severing and arranging means, and more particularly to a novel, inexpensive and simple arrangement for sub-dividing a web, bearing printed or recorded subject matter generally in page form, into sheets arranged in a predetermined manner.

The problem of handling a web issuing from a printing or recording machine of any type, so that subject matter recorded in page form will be available for inspection and perusal, has been imperfectly solved in the prior art by complicated and hence costly devices whichhave not been entirely satisfactory. In accordance with the present invention a web or strip as it issues from a recording machine is conveniently disposed in roll form in such a manner that by performing a simple severing operation a booklet of sheets arranged in a predetermined order is formed and the pages of the resulting booklet may be secured together in any known or suitable manner.

Accordingly, the primary object of the present invention is to provide novel and simple means for predetermining the arrangement of sheets severed from a web of recorded matter in such a manner that the sheets need not be handled for the purpose or arrangement.

Another object of the present invention is to provide a novel form of take-up roll for a printed or recorded web or strip.

A further object of the invention is to provide mechanism in the form of an attachment which may be readily applied to existing printing and recording devices in a fixed or adjustable position with respect to the recording means.

- Still another object of the invention is to provide a normal drive arrangement for a take-up roll associated with a printing or recording mechanism.

A still further object of the present invention is to provide a novel sheet severing device for severing sheets from a continuous strip so that each severing operation occurs at least approximately in register with subject matter spaced at definite intervals on the strip.

The foregoing and other objects of my invention will be brought out more in detail in the fol-' lowing description of several illustrative embodiments of the invention, reference being had to the accompanying drawings in which:

Fig. 1 is a view in perspective of a printer or recorder provided with the take-up roll and sheet severing device of this invention.

Figs. 2 and 3 arefragmentary detailed showings of the device of Fig. 1.

Fig. 4 is a diagrammatic view in side elevation 2 Claims. (Cl. 242-56) 2 of a slight modification of the arrangement of Fig. 1. I

Fig. 5 is a view in front elevation of the device of Fig. 4.

Figs. 6 and 7 are elevational and sectional views of a web severing tool.

Referring to the drawings, and more especially of Fig. 1 thereof, it] represents a casing in which is housed a printing or recording device (not shown) such as a facsimile telegraph receiver of the type which records received subject matter on a web or strip of paper i I, which is fed out through a slot l2 as the printing or recording operation proceeds. The printing or recording mechanism in the casing it, it will be understood, may be a page printing telegraph machine, a rotary printing press or a facsimile recorder of any type as above stated. The portion of strip ii which is visible On Fig. 1 is shown as having page material 15 recorded successively, that is, the line or unrecorded strip designated M is the end of one page and the beginning of the next succeeding recordedpage. If desired, the recording apparatus may be arranged in such a manner as to print or record the line or strip Id, or the runout mechanism of the printer or recorder may space the page recordings along the web or strip.

The strip of recording may be provided at intervais with printed matter forming the headings of integrally with a metal plate or the like I9, which t has -a downwardly turned portion 2i arranged to be clamped against the front of the'casing iii: by

suitable fastening means such as screws 22'. The portion 2| is or may be slotted as indicated at 23 to provide lateral adjustment for the support plate 19 so that the take-up roll [6 maybe in position axially to receive the paperwebt :H from;

the slot l2 without wrinkling or. other: distortion.

A severing device later to be describedqis conveniently supported on an upturned portion 24 of the plate l9. i

The shaft ll extends beyond the bearing bracket I8 to the right as shown and terminates in a crank 25 which may be manipulated to position the roll angularly when a severing operation is'to be performed. The shaft l1, and with it the roll l9, may be rotated in direction of the arrow by means of a worm 21 and worm wheel 28 driven from a shaft 29 which projects into the casing I and is in turn driven by some rotating part of the printing or recording mechanism. The worm wheel 28 preferably drives the shaft l'l through a slip clutch mechanism ll of any suitable type so that the shaft l1 may be stopped when desired by engaging a pawl 26 with a tooth of a ratchet wheel 26' secured to the end of the shaft which projects beyond the lefthand bracket it. As an alternative arrangement, it will be understood that the shaft 29 may be driven through a clutch capable of operation by" any suitable handle arrangement projecting from the casing III to a conveniently accessible position.

Referring to Figs. 2 and 3, which show the severing arrangement more in detail, a member 82 is slidably mounted in a slot 33 between the inwardly directed edge of the plate portion 24 and the inwardly turned edge of an elongated angle shaped member 36, which is secured to the portion 24 in any suitable manner. The slidable member 92 has pivoted on it a lever 31 ending in a handle or thumb piece 38. A spring 99 biases the lever and a severing wheel 42 rotatably carried thereon away from the periphery of the roll IS. The severing wheel 42 is preferably provided with sharpened teeth 43 so as to perforate and sever superposed layers of the sheet II when the thumb piece is pressed inwardly and the entire assembly is moved axbe engaged with the ratchet wheel 28', after the crank has been used to bring the visible strip l4 under thewheel 42.

Figs. 4 and 5 of thedrawings disclose a modifled arrangement which may be entirely hand operated or driven by a motor such as a spring motor 46 of any suitable type. Parts corresponding with those in Fig. 1 will be designated by the same reference character with the sufllx 0 added. Fig. 4 shows by way of example a recording arrangement comprising a paper feed storage roll 41, a paper .moistening roll 48 and a facsimile recording scanner 49, which may be of any desired type.

A number of guide rollers 5i serve to guide the record strip Ila in its passage over the different elements of the recording mechanism. While the device 49 has been referred to as facsimile recording scanner, it will be understood that this ially 'of the take-up roll [6. It will be understood that the wheel 42 may be provided witha sharpened edge rather than the teeth shown and described.

In accordance with the invention the circumference of the take-up roll I6 is approximately equal to the length of a recorded page i5, that is to say, the approximate distance between lines i4 on the web II. This roll it is corrugated as shown so as to facilitate the severing operation, which is performed as pointed out above by pressing the thumb piece inwardly and moving the severing wheel 42 axially of the roll I6.

In operation of the arrangement just described, one turn or more of the strip II will be wrapped on 'roll it, using the handle 25 for this purpose, the pawl 26 being released from engagement with the ratchet 26. If the printing or recording mechanism in the casing Ill is of the type which is provided with a run-out release, this step may be performed after a length of unrecorded strip projects through the slotl2. After the strip H is started on the roll I6 the winding operation will be continued by reason of rotation of the shaft 29. It will. be noted that when roll' I6 is driven in the manner described above, no tension will be placed on strip II which may be of advantage when' certain types of printing or recording mechanisms are employed. Inasmuch as the circumference of the roll it is substantially equal to the length of a recorded page, when the severing wheel "is drawn across the roll ii after the recording of a number of sheets, for example, after all of the pages of a given series have been recorded, the severed sheets will be stacked and in their correct sequence when they are removed from the roll after the cutting operation. They may then be stapled or otherwise secured together in convenient booklet form.

During the cutting operation the pawl 26 w l may be the platen of a printing telegraph machine, a typewriter or the impression roll of a printing press. The web Ila is shown as being fed outwardly through a slot l2a in the casing, as fragment of which is indicated at Illa. The take-up roll lSa may be similar in all respects to the roll iii of Fig. l, and if desired may be supported in the same manner. The spring motor 46 may be wound in the usual manner by a crank or winding key 52. A crank 53 serves the purpose of the crank 25 of Fig. 1. It will be understood that if desired the spring motor 46 may be omitted entirely, and in that event the roll may be used to obtain a number of superposed discrete pages in a desired order by winding a portion of the recorded strip I la on the reel "5a and using a separate cutting tool such as is shown in Figs. 6 and '7 of the drawings to sever these superposed layers.

Referring to Figs. 5 and 6 showing a tool designed to be used in cooperation with roll l8 for cutting a sheet or web rolled thereon, reference character 54 designates a channel shaped member of sufllcient length to serve conveniently as a handle. A toothed perforated or edge sharpened wheel 56 is rotatably carried on a pintle 51 mounted in the sides of the channel. The manner of using this tool will, it is believed, be obvious from the foregoing.

Having now described the invention, what I claimis:

1. In combination with a recorder which records subject matter on a continuous strip, a take-up roll for said strip, drive means, means for rotating said roll from said drive means including a slip clutch, a cutting element movable axially of said roll for cutting the material of said strip while on said roll, said roll being corrugated for the purpose of accommodating said cutting element as it projects through the material of said strip during a cutting operation.

2. In a. facsimile machine, means for marking a record strip along its length, a take up roll for receiving and forming said record strip into a roll as the said strip is discharged from said marking means, drive means for rotating said take up roll, a severing element associated with and movable axially of said take up roll for penetrating through the superposed layers of said strip in said formed roll thereby to facilitate separation of portions of said strip into a plurality of sheets arranged in the order of marking, and said takeup roll being provided with corrugations spaced around the periphery thereof for the purpose of accommodating said severing element as it projects through the material of said formed r011 during a severing operation,
